1. An audio/video control system comprising:
a plurality of audio/video devices that include a core device and a first device different from the core device, the core device and the first device being interconnected by a digital audio/video interface, both of the core device and the first device being connected to a network without using the digital audio/video interface, the digital audio/video interface and the network being different from each other; and
a portable terminal device that is connected to the network,
wherein the core device includes a first processor for executing stored instructions to:
collect interface-connected device information of at least the first device from at least the first device via the digital audio/video interface, the interface-connected device information including at least unique identification information;
generate a connection device table using the collected interface-connected device information; and
transfer the connection device table to the portable terminal device; and
the portable terminal device includes a second processor for executing stored instructions to:
search the network and acquires network-compatible device information including network addresses and unique identification information of devices on the network;
generate a network compatible device table using the acquired network compatible device information;
directly communicate with the core device via the network without using the first device to acquire, from the core device, the interface-connected device information of at least the first device;
compare and associate the network-compatible device information included in the network compatible device table and the interface-connected device information included in the connection device table to resolve a network address of at least the first device;
display an optional screen that accepts an operation by a user on the portable terminal device; and
directly transmit, to the first device, a control command for controlling the first device via the network using the resolved network address of the first device without the control command passing through the core device.
